This paper outlines the development of an index of child well-being using data from the first wave of the Child Cohort in the Growing up in Ireland study. This national longitudinal study explores children’s lives by collecting data from 8,568 nine-year-old children, their caregivers and their teachers. Well-being indices are useful to describe children’s circumstances, to monitor child outcomes, and to create and assess the efficacy of social polices involving children. Traditionally, macro-level data has been used in the construction of child well-being indices. However, micro-level data is used in this paper to provide a child-centered perspective on their well-being. This index is comprised of three domains; physical health, social & emotional functioning and educational attainment. Fourteen measures were used in the creation of these domains utilising data from children, caregivers and teachers on the child’s current development. The domain content, protocol followed and confirmatory pro-cess used in creating this index are discussed. Evidence is provided supporting the inclusion of the domains and the factorial structure of the index. A child well-being index of this sort is valuable as it manages to efficiently summarize the richness of information provided by multiple informants on the multidimensional nature of child well-being into a single index. Consequently, it can be easily used and understood by the various stakeholders involved in services related to child welfare.

Internationally and in Ireland, much of the research around gender and educational engagement has centred on the academic differences between boys and girls (Warrington and Younger 2000; Francis 2009; O’Connor 2007). Less is known however about the factors shaping affective school engagement and student self-concept and how this can affect participation in learning. Children and young people emphasise the affective or emotional as much as the learning aspects of school life (Alexander 2008). Drawing on data from the 9-year cohort of the Growing Up in Ireland study, this paper examines self-concept among boys and girls in Irish primary schools. The findings show important differences in terms of the affective elements of school engagement, with boys more likely than girls to score significantly lower levels on measures of ‘good’ behaviour and intellectual school status, while girls score significantly lower on freedom from anxiety than boys. The findings also illustrate that predictors of disengagement are about more than the child’s gender – in that working class children and students with special educational needs are faring less well in terms of affective engagement in school.

The Growing Up Healthy in Families Across the Globe project is an international collaboration examining the potential for harmonised analysis using five longitudinal studies (from New Zealand, Ireland and Scotland). All five studies follow the lives of children, are interested in the dynamics of family change and work to inform policy to potentially improve population well-being across the life-course. Comparative analysis from harmonised longitudinal studies, where change over time is emphasised, provides a unique view to determine how and why environments change, which environments are supportive and which are not. This paper discusses the challenges and tasks involved when preparing and conducting harmonised analysis, and initial findings from the Growing Up Healthy project are discussed. The studies were, from New Zealand, Te Hoe Nuku Roa, the Pacific Island Families Study and Growing Up in New Zealand, and from Scotland and Ireland Growing Up in Scotland and Growing Up in Ireland. Post hoc data harmonisation of measures resulted in the identification of several closely aligned variables. The harmonised descriptive variables from the five studies highlight many similarities across the studies. A risk factor model to predict child development outcomes (using the Strengths and Difficulties Questionnaire) was developed and resulted in very similar patterns of risk in New Zealand, Ireland and Scotland. Risks included: maternal relationship status, maternal education, smoking in pregnancy, maternal self-reported health and maternal long-standing illness. The insights will be of interest to all those concerned with child development in contemporary New Zealand, Ireland, Scotland and other similar countries.

Children with disabilities experience significantly poorer socio-emotional outcomes than their peers without disabilities. However, research evidence is scarce about children with both disability and migration background, the group which this study aimed to investigate using data from a national longitudinal study. Secondary data analyses were conducted on a sample of 7290 children (weighted with missing values imputed). Significant differences in socio-emotional outcomes were found in relation to impairment status but not in relation to migration. Having an impairment and activity limitation significantly increased the likelihood of experiencing poorer socio-emotional outcomes over time. Our findings highlight a higher risk of socio-emotional problems among children with disabilities, especially among children from lower income backgrounds and with parents with lower educational attainment. These findings clearly require policy development on two fronts: to raise professional and community awareness on these issues and to strengthen the capacity of health, education and social care systems to support schools, families, and communities.

In this paper we make use of the 9-year-old wave of the Growing Up in Ireland study to analyse multidimensional deprivation in Ireland. The Alkire and Foster adjusted headcount ratio approach (AHR; Alkire and Foster, Journal of Public Economics, 95, 476–487, 2011a, Journal of Economic Inequality, 9, 289–314, 2011b) applied here constitutes a significant improvement on union and intersection approaches and allows for the decomposition of multidimensional poverty in terms of dimensions and sub-groups. The approach involves a censoring of data such that deprivations count only for those above the specified multidimensional threshold leading to a stronger set of interrelationships between deprivation dimensions. Our analysis shows that the composition of the adjusted headcount ratio is influenced by a range of socio-economic factors. For less favoured socio-economic groups dimensions relating to material deprivation are disproportionately represented while for the more advantaged groups, those relating to behavioral and emotional issues and social interaction play a greater role. Notwithstanding such variation in composition, our analysis showed that the AHCR varied systematically across categories of household type, and the social class, education and age group of the Primary Caregiver. Furthermore, these variables combined in a cumulative manner. The most systematic variation was in relation to the headcount of those above the multidimensional threshold rather than intensity, conditional on being above that cut-off point. Without seeking to arbitrate on the relative value of composite indices versus disaggregated profiles, our analysis demonstrates that there is much to be gained from adopting an approach with clearly understood axiomatic properties. Doing so allows one to evaluate the consequences of the measurement strategy employed for the understanding of levels of multidimensional deprivation, the nature of such deprivation profiles and socioeconomic risk patterns. Ultimately it permits an informed assessment of the strengths and weaknesses of the particular choices made.

The relationship between parental background and children’s educational outcomes has been a dominant theme within the sociology of education. There has been an on-going debate as to the relative merits of explanations which focus on the role of socio-cultural reproduction and those which focus on rational choice. However, many empirical studies within the social stratification tradition fail to allow for children’s own agency in shaping the relationship between social background and schooling outcomes. This paper draws on the first wave of a large-scale longitudinal study of over 8,000 nine-year-old children in Ireland, which combines information from parents, school principals, teachers and children themselves. Both social class and parental education are found to have significant effects on reading and mathematics test scores among nine year olds. These effects are partly mediated by home-based educational resources and activities, parents’ educational expectations for their child, and parents’ formal involvement in the school. More importantly, children’s own engagement with, and attitudes to, school significantly influence their academic performance. The influence of children’s own attitudes and actions can thus reinforce or mitigate the effect of social background factors. The analysis therefore provides a bridge between the large body of research on the intergenerational transmission of inequality and the emerging research and policy literature on children’s rights.

This study uses a nationally representative sample of 9-month-old infants and their families from the Growing Up in Ireland (GUI) study to investigate if reading to infants is associated with higher scores on contemporaneous indicators of cognitive development independently of other language-based interactions between parent and infant, such as showing them pictures or talking to them. Reading to infants had an independent positive effect on scores for both the problem-solving and communication subscales of the Ages and Stages Questionnaire (ASQ), while the positive effect of showing pictures was independent only for communication scores. The effects of both of these activities were, however, less substantial than the positive effect observed for the more informal activity of frequently talking to the infant while doing other things; and this was observed for both communication and problem-solving. The analyses were robust to adjustment for several other factors including maternal education, gestational age, non-parental care, breastfeeding, attachment and presence of siblings. The findings highlight the potential of reading and talking to infants, not just for language and literacy development but also for other aspects of cognitive development.

Background
Preventing child mental health problems and child obesity have been recognized as public health priorities. The aim of the present study was to examine whether being breastfed (at all or exclusively) in infancy was a predictor of mental well-being and protective against risk of obesity at age 9.

Methods
Cross-sectional data from a large, nationally representative cohort study in the Republic of Ireland was used (n = 8357). Data on breastfeeding were retrospectively recalled. Child mental well-being was assessed using a parent-completed Strengths and Difficulties Questionnaire (SDQ). Child’s height and weight were measured using scientifically calibrated instruments.

Results
Logistic regression analyses indicated that, after controlling for a wide range of potential confounding variables, being breastfed in infancy was associated with a 26% (P < 0.05) reduction in the risk of an abnormal SDQ score at 9 years. Being breastfed remained a significant predictor of child mental well-being when child obesity was controlled for, indicating that being breastfed, independent of child obesity, is a predictor of child mental well-being. The results of a second logistic regression indicated that, after controlling for a wide range of potential confounding variables, being breastfed for between 11 and 25 weeks was associated with a 36% (P < 0.05) reduction in the risk of obesity at 9 years, while being breastfed for 26 weeks or longer was associated with a 48% (P < 0.01) reduction in the risk of obesity at 9 years.

Conclusions
Breastfeeding in infancy may protect against both poor mental well-being and obesity in childhood.

Background
Parental incarceration (PI) is associated with adverse developmental outcomes for children affected. However, research in this area often reports conflicting results with few studies following children across time in non-U.S. populations. Additionally, more research is called for using multi-informant perspectives rather than relying on adult reports of child outcomes alone.

Methods
This study used data from the first two waves of a nationally representative cohort study of 8,568 children aged 9 years and followed up at age 13 living in the Republic of Ireland (2007–2012). Propensity score matching was used to match children who had experienced PI by the age of nine to children who had not experienced PI by sociodemographics and experience of other stressful events. Mental health, as measured by self-concept (Piers-Harris II) and externalizing and internalizing difficulties (strength and difficulties questionnaire), was compared across both groups.

Results
Fifty of the 8,568 children (weighted percentage 0.9%) reported experiencing PI by the age of nine. These children came from more socially disadvantaged homes and were more likely to have experienced other potentially stressful life events. In comparison to a matched sample of children not affected by PI, children affected by PI reported higher levels of anxiety at age nine. Longitudinal analysis indicated these children affected by PI also reported lower levels of happiness at age 13 with higher levels of emotional difficulties reported by their primary caregiver.

Conclusions
Children of incarcerated parents face a greater array of life challenges. PI had an association with child-reported levels of anxiety at age nine. PI also had a medium-term association on caregiver assessments of emotional difficulties of children affected as well child-reported levels of happiness over time.

Both psychological and sociological accounts have suggested that the home learning environment play an important role in children’s cognitive development and may provide insights into inequalities in cognitive outcomes. Using the infant cohort of the Growing Up in Ireland Study (GUI), this chapter investigates firstly if differences in the home learning environment at age three helps to explain the social gradient in childhood cognitive outcomes, measured as expressive vocabulary, at age five; and second, can childcare outside the home compensate for a poor home learning environment? Home learning environment is measured as the number of children’s books in the home and a combined index of parental activities with the child that includes reading, crafts and games. A rich home learning environment at age 3 is associated with higher vocabulary scores at age 5 years for all children. The children of lower educated parents tend to live in poorer home learning environments, and this partly explains their lower vocabulary scores at age 5. The chapter also provides some evidence that centre-based childcare was associated with an increase in vocabulary score for children from poor home learning environments. However, this effect is very small and only slightly reduces the gap in vocabulary scores between children from a rich and poor home learning environment.

Background
Adolescence is a critical transition point for body weight. Personality traits are associated consistently with weight and obesity risk in adulthood. We examined whether personality, particularly Conscientiousness (the tendency to be organized, disciplined, and responsible), is associated with weight outcomes between ages 13 and 17.

Methods
Data are drawn from the Growing Up in Ireland suites of studies. Parents rated their child’s personality at age 13, and trained staff measured weight and height at ages 13 and 17 (N = 4962). Logistic regression was used to predict risk of incident obesity and obesity remission between ages 13 and 17.

Results
Among children who were not in the obesity category at age 13, higher Conscientiousness was associated with lower risk of moving into the obesity category by age 17, and, among children with obesity at age 13, Conscientiousness was associated with greater likelihood of moving to the nonobesity category by age 17. These associations were independent of sociodemographic characteristics, parent body mass index, and were similar across gender. The other five-factor model personality traits were unrelated to weight outcomes.

Conclusions
Conscientiousness is one trait psychological factor implicated in weight transitions across a critical period during adolescence.

A small proportion of children experience social-emotional difficulties from early childhood onwards. Longitudinal studies with nationally representative samples are needed to identify the prevalence and the characteristics of children and families persistently experiencing these difficulties. Secondary analysis of data collected on over 7500 Irish children and with the Strengths and Difficulties Questionnaire as the primary indicator, found that 6% of children when they were five year olds and 8% when they were nine-years, had above threshold scores that warranted further investigation. A smaller proportion—2.9% had elevated scores at both ages. Logistic regression analyses found that children with one or more developmental disabilities were up to six times more likely to have sustained difficulties. There were also significant associations with the lower education attainment of primary caregivers and the socio-economic deprivation of families. Primary caregivers and teachers reported higher conflict in their relationships with these children. Although the number of Irish children presenting with continuing social-emotional difficulties is small, they can present an ongoing and future societal cost in terms of the impact on family relations and demands placed on educational, health and social services. This study identified the children and families who are at greatest risk and for whom targeted early intervention services could be provided.

The sudden health and economic crisis brought about by the COVID-19 pandemic affords an opportunity to examine the impact of economic disruption to children and families. Any negative effects on the well-being of children are important to consider in relation to both short- and long-term outcomes. Using pre-pandemic and mid-pandemic waves of the longitudinal Growing Up in Ireland study, we examined whether the impact of economic disruption was equivalent for families who were (or were not) financially vulnerable pre-pandemic. We then investigated whether economic disruption was associated with a negative effect on the emotional well-being of 12-year-olds, and if there was evidence for such a negative effect being mediated through a lack of material resources or strain on family dynamics. Our results indicated that middle-income rather than lowest-income families experienced the most economic disruption, likely reflecting the sector-specific nature of business closures in the pandemic. Families who were financially vulnerable pre-pandemic were less likely to have had suitable resources for homeschooling. Both falls in income and strain in family relationships, such as arguing more with their parents, were associated with poorer scores on a measure of the child’s emotional well-being. The emergency income support payment introduced at the start of the pandemic appeared to have a protective effect on the association between family income loss and child well-being, which has wider implications for policy on child poverty.

With screen use becoming more prevalent at a younger age, it is important to research the possible impact screen use has on early cognitive development. The current study examines the screen use of 9001 5-year-olds and their reasoning abilities, using data from the Growing Up in Ireland study. Results show that both the amount of daily screen time, along with the type of screen activity children mostly engage in (video games, educational games, TV/video watching, or a mix of all of these activities), have an impact on 5-year-olds’ reasoning ability. Children who mostly engaged in a mix of activities for under three hours a day scored higher on a reasoning ability task than those who engaged in more than three hours of screen time, or those who engaged in an individual screen activity (e.g., television watching) rather than a mix of activities. However, the results also show screen use plays a very minor role in the development of reasoning ability. Consequently, other factors (e.g., home learning environment, parental education levels) should also be investigated when examining the role of screen use in cognitive development. The implications of these findings may therefore be of interest to parent, educators and policy-makers.

This paper examines multidimensional poverty for three waves of a cohort of Irish children ranging from ages 9 to 17. Poverty is measured over the dimensions of health, education and family resources and both unidimensional and multidimensional poverty is examined. Both show a clear gradient with respect to maternal education. The dynamics of both unidimensional and multidimensional poverty are also analysed. The greatest degree of mobility is observed with respect to family resources. Mobility also is higher for children whose mothers have lower levels of education, with net movements into rather than out of poverty.

Objectives
To assess the impact of digital media usage on psychiatric symptoms in an adolescent population utilizing a longitudinal cohort design.

Methods
Using two waves of the GUI child cohort, age 13 (N = 7527) and age 17/18 (N = 6126), we used latent class analysis (LCA) to create latent groups centred around self-reported time spent online, and the self-reported behaviours children engaged with online. At both waves, the 4 class latent model suited best. We used the different symptoms scales of the Strengths and Difficulties Questionnaires (SDQ), self-reported, at age 17 as our outcome variable. Using linear regression analysis, we then examined the associations between our latent class model and psychiatric symptoms, using moderate usage as our reference group, with adjustments being made for baseline psychiatric symptoms, maternal education and pre-diagnosed mental disorder.

Results
For females, placement in the high usage group at 13 was associated with increased internalizing symptoms, whereas placement in the high usage group at 17 was associated with an increase in all symptoms. For males, placement in the high usage group at 17 was associated with increased emotional symptoms, and placement in the “low usage & behaviour engagement”group, a group showing low reported time online and low engagement in our measured online behaviours at 17, was associated with an increase in all symptoms. Finally for both sexes, placement in the “moderate usage, entertainment only” group at age 13, (a group reporting no school-based online engagement), was associated with increases in all symptoms except emotional symptoms.

Conclusion
High digital media usage is associated with increased psychiatric symptoms in both males and females, with moderate usage associated with positive effects on symptoms compared to both our high usage, and low usage groups.

Whilst there is a large evidence base demonstrating the impact of maternal depression on the development of adolescent internalising problems, less is known about the association between paternal depression and adolescent internalising problems, and the mechanisms through which risk is conferred. This study examined the association between paternal depression and adolescent internalising problems, investigating parenting style as a pathway through which this association may be mediated. Participants included 4048 families taking part in the Growing Up in Ireland child cohort study. Self-report measures of paternal depression were completed when the study child was aged 9. Adolescents assessed paternal demandingness, responsiveness and autonomy granting at the age of 13. Adolescent internalising symptoms were measured at the age of 17/18 by the primary caregiver. A parallel multiple mediator model was used to test the total and specific indirect effects of the three parenting styles, whilst controlling for covariates and other mediators in the model. A direct effect of paternal depression on adolescent internalising problems was found (B = .051, 95% CI: 0.020, 0.083). However, no support for mediation via any of the paternal parenting styles (i.e., responsiveness, demandingness, or autonomy-granting) were found. These findings build on an emerging evidence-base demonstrating a specific direct association between paternal depression and adolescent internalising problems, and suggest that interventions ought to also target fathers suffering from depression to help reduce the risk of adolescent internalising problems.

Family and home environment factors have been outlined in previous literature as important variables that affect early reasoning development. However, little research has focused on the association between screen use in the home environment and nonverbal reasoning ability. The aim of this cross-sectional study is to examine the role of both screen time and various screen activities (e.g., television, video, or educational games) in nonverbal reasoning ability in 9,001 5-year-old children using a large birth cohort study (Growing Up in Ireland). Interviews conducted with parents related to the children’s screen use and various family factors, while reasoning ability was measured using a standardized task (Picture Similarities Task, British Ability Scales II). A hierarchical multiple regression examined the role of screen use in nonverbal reasoning, while also statistically controlling for family factors such as parental education and employment status. Screen use variables made a significant contribution to the regression model, even after family factors were accounted for, although the effect sizes were very small. Playing educational games, video games, or engaging in over three hours screen use per day were all significant predictors of nonverbal reasoning scores in the final adjusted model. The results of this study suggest that screen use may play a small role in the development of nonverbal reasoning in young children. The findings highlight the need for further studies in this area and may have implications for current debates in screen time research.
